In earlier times, most people of humble means lived in cottages or single-storey farmhouses. These were built using tradional methods and traditional materials. Walls were made of mud or turf or stone, reinforced sometimes with wooden crutches called crucks, and rooves were thatched. This type of building is called vernacular architecture.
Grander, two-storey thatched farmhouses are often called planter-style houses. They were usually made in stone, were thatched, and were rendered and whitewashed.
